2488“…The three acetoxy groups in each molecule are essentially planar and are tilted, in a regular propeller-style arrangement, with their normals oriented between 56.72 (12) and 76.35 (9)° from the normal to the mean plane of the central C(6) ring; in each molecule the three carbonyl O atoms are on the same side of the C(6) ring, with the C(ring)—O—C—Me bonds in a trans conformation. The principal intermolecular contacts appear to be C—H⋯π-ring interactions; each C(6) ring has such a contact to both faces of the ring; in addition, each molecule has two intermolecular C—H⋯O contacts with H⋯O distances less than 2.55 Å.…”

2490“…The title compound, [Rh(C(10)H(7)N(2)O(2))(C(18)H(15)P)(CO)]·(CH(3))(2)CO, is the second structural report of a metal complex formed with the O,O′-C(10)H(7)N(2)O(2) (neocupferrate) ligand. In the crystal structure, the metal centre is surrounded by one carbonyl ligand, one triphenylphosphine ligand and the bidentate neocupferrate ligand, forming a distorted square-planar RhCO(2)P coordination set which is best illustrated by the small O—Rh—O bite angle of 77.74 (10)°. …”
